We review recent work on the use of the slice energy concept in generalizedtheories of gravitation. We focus on two special features in these theories,namely, the energy exchange between the matter component and the scalar fieldgenerated by the conformal transformation to the Einstein frame of suchtheories and the issue of the physical equivalence of different conformal framerepresentations. We show that all such conformally-related, generalizedtheories of gravitation allow for the slice energy to be invariably defined andits fundamental properties be insensitive to conformal transformations.Comment: 16 pages, In: Proceedings of the 11th Greek Relativity Meetin
